JOHN A. AUE, OF FREEPORT, ILLINOIS, ASSIGNOR TO HARRISON VVOODMANSE, OF FREEPORI, ILLINOIS.

TIGHTENER FOR BRACE-RODS.

Specification of Letters Patent.

Patented Oct. 24:, 1905.

Application filed July 18, 1905. Serial No. 270,303.

To all 'I/U/l/O'I'H/ it 171,041 0071 06772,:

Be it known that I, JOHN A. AUn, a citizen of the United States of America, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Tighteners for Brace-Rods, of which the following is a speci lication.

The object of this invention is to provide means for tightening diagonal brace-rods as, for instance, the crossed brace-rods in windmill-towers, to which this invention particularly relates.

In the accompanying drawings, Figure 1 is a side elevation of a section of a windmilltower having the brace-rods thereon tightsued by means of my improvement. Fig. 2 is an enlarged section, at the dotted line 2 2 in Fig. 1, of parts there shown. Fig. 3 is a full-sized isometrical detail view of the clampbody of the tightener.

Like letters of reference indicate corresponding parts throughout the several views.

A represents angle-iron corner-posts of a windmill-tower. B represents angle-iron cross -girths securely connecting them together.

O represents crossed brace-rods (attached at their opposite ends by means of bolts or rivets I) to the adjacent and opposite corner-posts A) drawn tensely by applying force to their middle portions and forcing them in opposite directions in a plane parallel to their points of attachment 1).

E is the clamp-body of a tightener having a substantially X-shaped recess E therein to admit a brace-rod O, placed obliquely thereinto and provided with an upwardly-extending lug E to engage the downwardly-projecting member F of an angleiron cross-girth B.

G is a d-bolt engaging the free edge of the outwardly-projecting member H of such crossgirth B and extending through a transverse hole I in the clamp-body E. J is a nut applied to the threaded straight shank K of the d-bolt G to secure the bracerod 0 into the recess E in the clamp-body E.

After the parts of the tightener have been put together in the manner already described the brace-rods C are forced simultaneously in opposite directions until they are as tense as is desired and are then secured in such tense condition to the contiguous cross-girth B. They may be forced inward with identically the same results. Obviously whenever it is desired at any time to retighten any or all of the brace-rods C it can be done with ease and despatch.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a tightener for brace-rods, in combination, a clamp-body having a substantially X-shaped recess therein to admit a brace-rodplaced obliquely thereinto and provided with an upwardly-extending lug to engage the downwardly-projecting member of an angleiron cross-girth, a iJ-bolt engaging the free edge of the outwardly-projecting member of such cross girth and extending through a transverse hole in the clamp-body and a nut applied to the threaded straight shank of the iJ-bolt to secure a brace-rod into the recess in the clamp-body and the latter to such crossgirth, substantially as described.

2. In a tightener for brace-rods, in combination, a clamp-body E, having a substantially X-shaped recess E therein to admit a brace-rod, as O placed obliquely thereinto and provided with an upwardly-extending lug E to engage the member F of an angleiron cross-girth, a tl-bolt G engaging the free edge of the outwardly-projeeting member H of such cross-girth and extending through a transverse hole I in the clamp-body E, and a nut J applied to the U-bolt to secure a bracerod, as G, into the recess E in the clampbody E and the latter to such crossgirth, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
